remember: conventional current uses positive charge carriers; positive charge carriers obey the right hand rule in a magnetic field; negative charge carriers obey the left hand rule in a magnetic field => using the hall effect one can measure if a semiconductor is a p-type or an n-type as well as the mobility of the material

man.. don't bring that up! I hated memorizing that stuff in class. i'm just happy to memorize the dopants that make up p or n type. despite that I still can't remember what type arsenic was.
actually remembering the dopant types is much, much easier with a periodic table. if it is to the right of silicon it makes it n-type (further right means more electrons in the outer shell); if it is to the left then it is p-type (less electrons in outer shell, or more holes). so arsenic is a p-type. where it gets confusing in trying to figure out n and p is the organics. i'm not sure how or if they predict what type an organic molecule is.
